Code Description

ICD-10 D39.11 is a billable code used to indicate a diagnosis of neoplasm of uncertain behavior of right ovary.

Key Diagnostic Point:

A neoplasm of uncertain behavior of the right ovary refers to a growth or tumor that arises from the ovarian tissue but does not exhibit definitive characteristics of malignancy or benignity. These neoplasms can present as cysts, solid masses, or complex lesions and may be discovered incidentally during imaging studies or surgical procedures. The behavior of these neoplasms is classified as uncertain due to the lack of clear histological features that would categorize them as benign or malignant. Surveillance is crucial, as some neoplasms may have the potential to progress to malignancy over time. Regular monitoring through imaging and clinical evaluations is recommended to assess any changes in size or characteristics. The management of these neoplasms often involves a multidisciplinary approach, including gynecologists, oncologists, and radiologists, to determine the best course of action, which may include watchful waiting, surgical intervention, or further diagnostic testing.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in histological findings
  • Need for ongoing surveillance and monitoring
  • Potential for progression to malignancy
  • Documentation of imaging and clinical findings

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to document surveillance plans
  • Misclassification of neoplasm behavior
  • Lack of follow-up notes

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed imaging reports, pathology results, and clinical notes regarding the neoplasm's behavior and management plan.

Common Clinical Scenarios

Incidental findings on ultrasound, follow-up of previously diagnosed neoplasms, and pre-operative assessments.

Billing Considerations

Ensure clear documentation of the neoplasm's characteristics and any changes over time to support coding and billing.

Oncology

Documentation Requirements

Comprehensive treatment plans, histopathology reports, and follow-up evaluations.

Common Clinical Scenarios

Management of neoplasms with uncertain behavior, including discussions on potential malignancy and treatment options.

Billing Considerations

Documentation must reflect the multidisciplinary approach and any consultations with other specialties.

Coding Guidelines

Inclusion Criteria

Use D39.11 When
  • According to ICD
  • 10 coding guidelines, D39
  • 11 should be used when the neoplasm's behavior is uncertain and specifically located in the right ovary
  • It is important to document the findings from imaging and pathology to justify the use of this code

Exclusion Criteria

Do NOT use D39.11 When
No specific exclusions found.

Laparoscopy, surgical, with removal of ovarian cyst

Clinical Scenario

Used when a patient with D39.11 undergoes surgery for evaluation or removal of the neoplasm.

Documentation Requirements

Operative report detailing the procedure, findings, and any pathology results.

Specialty Considerations

Ensure that the surgical indication aligns with the diagnosis of uncertain behavior.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking and management of these conditions, improving patient care and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking and management of these conditions, improving patient care and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking and management of these conditions, improving patient care and resource allocation.

Frequently Asked Questions

What does 'neoplasm of uncertain behavior' mean?

It refers to a tumor that cannot be definitively classified as benign or malignant based on current diagnostic criteria. These neoplasms require careful monitoring due to the potential for progression.
